Motion detection with an intelligent optical sensor with on-chip analogue memory
No full textA 64 x 64-pixel image sensor with full-frame analogue memory and on-chip motion processor is presented. The processor, consisting of a charge amplifier and an analogue subtractor realised with a switched capacitor technique, calculates the difference between the values of the signal on each pixel in successive frames at a rate of up to 60 frames/s with limited area and power overhead. Fabricated in a 1.2 ìm standard CMOS process with an added metal 3 light-shielding layer, the circuit is fully functional and requires a total core area of 13 mm
A Single-Chip Optical Sensor with Analog Memory for Motion Detection
No full textA 64x64-pixel image sensor with full-frame analog memory and on-chip motion processor is presented. The processor consists of a charge amplifier and an analog subtractor. It uses the switched-capacitor technique and calculates the difference between the values of the signal on each pixel in successive frames. The rate can achieve up to 60 frames/s with limited area and power overhead. The analog memory required for the storage of the previous frame is implemented using implanted capacitors placed within the sensor array. Fabricated in a 1.2-um standard CMOS process with an added metal 3 light-schielding layer, the circuit is fully funcional and requires a total core area of 13mm
